I've been having this issue for over a week now. For some reason. The alert mode on the firewall it's not working in Windows 11.it was working before i did a Bitdefender update I did all the troubleshooting that I could possibly do. I uninstall and reinstall Bitdefender. Uninstalled it with Bitdefender uninstaller tool. I reinstalled my whole Windows 11 setup. None of this worked. I think that A bit defender UPDATE has broken The alert mode feature and this is a really important feature for me. To keep me Protect it From the Internet. This is the reason why I purchased Bitdefender.
